後、作業者は管理区域へ立ち入る。For radiation workers working in nuclear facilities, the exposure dose must be limited for health reasons (the exposure dose is controlled by law). Figure 1 shows the configuration of the current exposure control device. In FIG. 1, reference numeral 11 is an automatic reading device installed at the entrance/exit of the radiation controlled area. Further, 12 is a central processing unit, which is combined with the automatic reading device 11 and performs radiation exposure processing. Then, at the entrance of the V-treatment area, the worker picks up the pocket dosimeter 13 that can memorize the exposure dose, and picks up the automatic reading device 1.
Insert into 1. Dosimeter 1 in the above automatic reading device 1
3. Operation check and entry information are exchanged. The worker then enters the controlled area.

持って管理区域から退出する。Workers always carry the dosimeter 13 while working in the controlled area, and the radiation exposure during this time is measured by the dosimeter 1.
3 is stored. After finishing the work, the worker inserts the a-pointer 13 into the automatic reading device 11. Accordingly, the automatic reading device 11 reads the exposure dose υ from the dosimeter 13 and transmits it to the central computing device 12. Thereafter, the worker leaves the controlled area with the dosimeter 13 in hand.
しかし、現行の被曝管理装置においては以下に述べるよ
うな欠点があった。However, current exposure control devices have the following drawbacks.

きない。1) When working in a place with a high radiation dose rate, it is necessary to manage the exposure dose in real time during work in order to reach the exposure limit value within a short time. However, the current system does not allow for easy control of the exposure level from the moment you enter the area to the moment you leave the area. Since it is a comprehensive management up to the point, lightning M cannot be done in the middle.
２）同一作業者が一回の入域で異なった作業を行なった
場合、作業種類別の被曝線量の内訳を管理することがで
きない。2) If the same worker performs different tasks in a single entry, it is not possible to manage the breakdown of exposure doses by type of work.

The upper limit value of the exposure l1M amount for which an alarm should be issued (hereinafter referred to as the alarm exposure dose value) is input from the keyboard 24, and the cumulative value of the exposure dose transmitted from the transceivers 33 to 35 is
When this value is reached, the calculation unit 21
~32 to transmit the ssK alarm signal to the transceiver 33~. Next, the transceivers 33 to 35 immediately transmit an alarm signal to the wireless dosimeter 39. By the way, the worker returns the wireless dosimeter 39 after completing work within the specified management area. At this time, the cumulative exposure dose value of the wireless dosimeter 39 is reset to a zero value in preparation for the next use. Next, the calculation unit 21 transmits the cumulative exposure dose data stored in the memory 22 to the writing unit 28 or 29. The writing unit 28 or 29 writes this data to the dosimeter 26 or 27 inserted in advance (for example, the current dosimeter 26
or added to the previously exposed dose value of 27). next,
The worker takes the current dosimeter 26 or 27, which has been added with the exposure dose in the specified controlled area, and leaves the specified controlled area. The worker then passes through the general controlled area and inserts the current dosimeter 26 or 27 into the automatic reading device ft32 installed at the entrance to the controlled area. Automatic reading device 1
reads the exposure dose and transmits it to the central computer 12.

る。Finally, the exposure control device described in the above embodiment can monitor individual exposure doses, working hours, t1''-reported exposure dose values, etc. not only after the worker leaves the building but also during work within the specified controlled area. The data can be monitored arbitrarily through the display unit 21 and can be printed out from the printer 25.Also, the specific management area can be divided into several zones (three locations in FIG. 2) and antennas can be arranged. It is possible to know approximately where the worker is working based on the number of the transmitter/receiver that is receiving the exposure data.It also remembers the transmitter/receiver number and reception time along with the exposure data. Therefore, by reproducing this data after completing work in a designated controlled area, it is also possible to analyze the amount of radiation the worker was exposed to at what position and at what time. .
